To all whom it may concern: i which is approximately triangular or wedge- Be it known that l, ABRAHAM Josniu sharp-1` in lorm.

'lhis wnstruction, or any other l'orm vise. olE gripping iace, may be substituted 'lior the The construction of the improvement will beveled iiaces shown in Figs. l to fl. be fully described' hereinafter in connection lt will be noted that the jaws 7 may be ai'- With the accompanying' drawing which liorms ranged in horizontal position llush with the a part of this specih'cation, and its novel ieaupper and lower surfaces of the jaws l and 2 tures will be defined in the appended claims. i

In the drawing', Figure l is a longitudinal as shown in Figs. l and 2, oi' in vertical posi tion, at right angles to the faces oi the jaws vertical section of a conventional form of vise, provided with the usual jaws, to which 1 and 2 as shown in Fig. 3. This result is Obtained by the use o'l the 'particular stein the improved removable and adjustable aws and socket arrangement shown, in conjuncare applied, Fig. 2 is a fragmentary per tion with the lact that the jaw members aie spective View showing the supplemental resecured in a position to abut against the gripmovable jaws in position upon the ordinary ping surfaces of the vise jaws, so that the vise aws, said removable jaws being in horijaw members may be placed in either one olE zontal position, Fig, 8 is a similar view showa plurality o'l positions with vrespect to the ing the removable jaws in vertical position vise jaws, but are positively held against with relation to the confronting 'laces ol: the i' main vise jaws, Fig. 4 is a perspective view ole :movement relative to said jaws when so positioned. Thus it will be apparent that the one of the removable jaws detached, and Fig. 5 is a similar view of a inodiiied forni of rework may be clamped between the gripping movable jaw.

The reference numerals 1 and 2 designate the usual coacting and opposing jaws ol5 a lt is obvious that pairs olE adjustable jaws having gripping surfaces oiE varying shape vise adapted to be relatively adjusted by a screw 3 and lever 4.

may be employed in connection with a single Each of the confronting faces o'lE the jaws 1 vise, so that one pair ol said jaws may be readily removed and"Y another pair substiand 2 is formed with a squared socket 5 to retuted as occasion ma f' ceive a correspondingly shaped stem 6, said stein projecting from the outer side oli the require. The invention comprises all such modificajaw members 7 Each jaw-member is iormed ol' a body portions and variations .in the details el" the imtion having parallel side faces and parallel provenieiit as may be resorted to without departing irom the terms and scope oi' the 'l'olend edge faces (excepting where one end lace is brought to a sharp edge), the side edgelowiiig claims.

lla-ving thus described my invention, what l claim as new is faces heilig inclined relatively to each other, l. '.lhe combination with a vise having one side edge-'face being at right angles to the end edge-faces, while the opposite side edge-face is at an acute angle to the end edge-faces, thereby providing a structure jaws, of a jaw member' removably carried by each o'l" the vise jaws, said jaw-members being complemental to each other, the connection between the vise jaw and its jaw member being formed to permit the member to be placed in either one of a plurality o' positions relatively to the vise jaw.

L'. The combination with a vise having jaws, each of said jaws having a socket in its gripping face, of a jaw member removably carried by each of the vise jaws, each jaw member having a projecting stem to 'fit the socket, the stem and socket being comple# mentally formed to permit the jaw member to be placed in either one of a plurality of positions with respect to its visey jaw, said member, when so placed, being 'positively held against movement relatively to its supporting jaw.

3. The combination with the main jaws oi' a vise, each 'formed on its inner face with an annular socket, of supplemental jaws removably seated in said socket, each of said supplemental `jaws having an angular stem to llit in the socket of the vise jaw, and having a straight edge on the face carrying the stem to fit against the face oi the vise jaw, the

opposite face oi' each of said supplemental jaws being at an acute angle to the rear face, forming a wide and a narrow end on each supplemental jaw, the stem and socket connection permitting the jaw members to be placed in either one of a plurality of positions with respect to the vise jaws, and be retained against movement relative to said ]aws.

4. A supplemental jaw Jfor vises, comprising a body substantially triangular in form, one side of which is at direct right angles to the ends and the other side of which is at an acute angle to the ends, and a stem carried by andlormed integral with that face of the jaw which is at right angles to the ends, substantially as described.
